This invention relates to grease packages.

The packaging of heavy greases and otherlubricants and the transfer of such grease from the package to its ultimate point of use, such for instance as into the transmission and diilerentlal cases of automotive vehicles, presents numerous problems, that, so far as known, have not been met previous to this invention. It has been common practice heretofore to provide a metal receptacle from which the grease was drawn by a hand or other pump, fromwhich latter in turn it was ejected by manual or other pressure into the case. The transfer from container to pump was always a smeary and messy operation, especially as, owing to limitations on pump and can sizes, it frequently had to be repeated several times for a single charge. Owing to the viscosity of such greases the complete lling oi the pump was practically impossible as the column of grease was interrupted by air pockets which made the emission of grease from the pump noncontinuous and sputtery performances, and,rof more importance, which militated against the exact measurements of the dispensed grease that are sometimes necessary.

It is among the objects of this invention. to provide a dispensing package for grease which is durable, strong, and of low manufacturing and filling cost; to provide a dispensing package for grease comprising a preserving chamber and a dispensing nozzle so arranged as to retain they grease in its chamber despite its manipulation and transportation until it is predeterminedly desired to have it pass through the nozzle; n to provide a non-metallic dispensing package for lubricants of strength'and durability such as can be stored for long periods without distintegration under the lubricant; to provide a cheap and effective dispensing package for'lubricants that can be used to contain and transport, then to dispense the lubricant, which can then be economically discarded; and other objects and advantages will become more apparent as the description proceeds. f

In the accompanying drawing forming part of this description:

There are certain problems incident to the packaging of both light' and heavy greases that l0 are more or less peculiar, but which must be accorded consideration in any attempt to package and dispense same. Oneis the destructive and disintegrating action of the materials on-certain proposed packaging materials, and the other l5 is the staining and smearing action of the goods. In conventional manual pumps where the pump cylinder has an end extendedl into an opened' can of grease, it is necessary that the pump cylinder be pressed down in the body of the lubricant as its piston is retracted in order to properly charge the cylinder against the dispensing outward stroke vof the piston.l This cannot be accomplished satisfactorily without getting some of the material on the outer surface'of the cylinder, 25 f with consequent unpleasantness to the operator.V The viscosity of the greases makes diillcult their' handling by the conventional pumping methods and devices. A

The invention herein comprises essentially a flexible compressible grease-tight, preferably nonmetallic, durable container withan associating dispensing nozzle in operative relation and of such small cost that the grease may be moved by manual pressure on the compressible walls of the container to urge .the grease outwardly through the nozzle, and which, when empty, may with economy be'discarded.

Referring to Fig. 1 there is disclosed a preferred but purely illustrative form of invention, 40 in which a cylinder of material such as a cellulose derivative such as Cellophane or the like, 4 hereinafter designated as. Cellophane, It, forms the oil and grease tight non-disintegratable in ner container tube or grease chamber. This cellophane chamber is preformed as a cylinder of the desired diameter, and at its outer end is crimped and sealed with suitable ties Il, assisted if need be by suitable cement or other adhesive. The cylinder is constricted at its other end by a suitable removable tie 12 so. that a predetermined measured quantity of the lubricant can be disposed between the two crimped constricted portions of the "Cellophane" cylinder. The cellophane cylinder carries on beyond the tie or wrap I2 in a more or less restricted crimped and iiexible dry conduit I3, the outer ilree end which is adhesively secured to the inner end I4 of a substantially rigid nozzle I5. It will be understood that the dry conduit I3 will be sealed Vin an oil-tight relation to the rigid nozzle by whatever means is found most expedient, such as by adhesives and -v by auxiliary restraining ties and the like (not shown). As a feature of interest the tie I2.constricting the dry conduit may connect with a cable or pull device I6 extending in parallelism with the conduit il and passing.

through a restricted hole il in the wall o! the rigid nozzle i5, to pass outwardly throughthe end of the nozzle I5. The tie I2 and pull string I6 are so arranged lthat upon pull on string i@ axially and outwardly of the nozzle the tie I2 willA be liberated and permit the lubricant contained in the cylinder I0 to enter the conduit I3 and to passthrough the nozzle I5.

' While it will be appreciated that the Cellophane container may be arranged as the ultimate cover for the lubricant, through the walls of which :the contained material may be observed for purposes of sale, yet for certain purposes it is contemplated that an outer protecting and reinforcing but fiexiblepreferably non-metallic housing will be provided. To this end a jacket I8, of duck, oilcloth, canvas, or other iiexible preferably woven material will be superimposed upon the inner receptacle, being fastened at one end by suitable twisted constricting means 2B and at the other by readily removable ties I9, and, in the weaving or other formation, being suitably restricted to fit ratherclosely both about the cylinder I8 andabollt the channel i3', to be constricted tightly upon the rigid nozzle I5 at the nozzle end by suitable constricting ties 2i. For safety it is contemplated that the sealing o the neck and of the nozzle can be combined. It

is contemplated that the external jacket l@ may be composed of a secondary Ce11ophane" 'wrapping which reinforces and strengthens the whole assembly without reducing the'visibility of the contained material. 'Ihe ties may be clamps or the like, as will be clear.

It will be clear that a highly satisfactory closure can be had by twisting the neck I3 oi' the cylinder and clamping it in its twisted relation by suitable means such as friction tape, clamps. or the like (not shown) and which latter is held against undesired opening by external ties I9 constricted about cover I8. Removal of the outer ties I9 permits the inner tie or clamp to be ruptured upon comparatively slight pressure on cylinder Ill, permitting the untwisting of the channel I3 and the free emission of the viscous contents.

The substantially rlgidnozzle Ii may be of any sort of material, whether oi' metal or composition material, and is preferabLv of such reduced outer diameter as'to be insertable into the conventional nlling openings in the cases to which they are applicable, but obviously has as large internal diameter as possible in order to restrict the ow as little as possible. It is of importance that when the nozzle has been inserted in the openinginthecasetobeillledorpartiallyillled.

, that inadvertent and accidental withdrawal oi' taining bands 2l and 25, in such manner that the nozzle may be pushed into operative disposition in the opening in the casing and will be held therein bythe lugs so as to require the bending of the lugs by an amrmative or positive pull to retract the nozzle. As shown in Fig. 3 a modified form of such retaining device may be found in the transversely disposed short wire 26 mounted in registering openings 2l in a modified nozzle 28. the operation of which will be clear. In Fig. 4 a transverse section through the nozzle is illustrated in which resilient wires 30 and 3i are disposed in longitudinal channels 32 crimped inwardly in a nozzle' 33, which is preferably elliptical in form so that the effective cross-sectional area is not diminished.

In every case a preferred form for the dispensing nozzle is a tapered tube witha circular cross-section at the small end gradually expanding into an elliptical cross-section toward the large end. The elliptical cross-section insures 20 clearance'between the dispensing nozzle and the circular lling hole, permitting excess lubricant to pass outwardly of the casing to be visible t0 the operator to indicate that the proper lubriI cant level has been reached within the casing. 25 As a further modiiled form of thevinvention a exible casing 38 is provided in Fig. 5 which is sealed by a constricting tie I0 or by other means. The casing 38 may be opened through a pull string 42 which is in connection with tie 4I 30 and extends outwardly through the nome di.

Another method of opening case 38 is with a nail (not shown) inseedv through the nozzle 6i, piercing casing 38. An external semi-impervious casing 83 houses the entire assembly 35 and serves as a dispensing neck for the lubricant. Casing 43 is tied permanently on the outer end and by a removable constricting tie 29 between casing 8% and the neck part of casing 13.

In Fig. 6 a i'urthermodied form of the invention is disclosed in that the nozzle 34 com' municates directly with the ilexible container chamber 3l, and is sealed by a threaded cap il@ or similar means. The lubricant content is maintained and stored in the chamber 3l and in the nozzle 36 at all times subject to the restraint of the cap 36. Obviously the outwardly sealed nozzle can be used with any form ot invention, and can replace the ties I2 and lt as well as the nozzles. 'I'he filling and sealing or the packages will be clear as well as the manifest advantagesod the package for storage, transportation and extrusion of the contents without expensive dilpensing apparatus and without soiling the operator in hands or clothing.
